Hello

Maybe, an test userChrome.css.

* Lesezeichen verwalten - Ordnericon liegend gelb */ @-moz-document url("chrome://browser/content/places/places.xhtml") { treechildren::-moz-tree-image(container) { list-style-image: url("file:///C:/Users/manag/AppData/Roaming/Mozilla/Firefox/Profiles/x1jkC9cC.Original profile/chrome/testyellowcolor.png") !important; } } /* Lesezeichensymbolleiste - Ordnericon liegend gelb */ @-moz-document url-prefix(chrome://browser/content/browser.xhtml) { .bookmark-item[container="true"] { list-style-image: url("file:///C:/Users/manag/AppData/Roaming/Mozilla/Firefox/Profiles/x1jkC9cC.Original profile/chrome/testyellowcolor.png")!important; --bookmark-item-icon: url("file:///C:/Users/manag/AppData/Roaming/Mozilla/Firefox/Profiles/x1jkC9cC.Original profile/chrome/testyellowcolor.png") !important; } } /*Lesezeichen in der Sidebar*/ @-moz-document url("chrome://browser/content/places/bookmarksSidebar.xhtml") { treechildren::-moz-tree-image(container) { list-style-image: url("file:///C:/Users/manag/AppData/Roaming/Mozilla/Firefox/Profiles/x1jkC9cC.Original profile/chrome/testyellowcolor.png") !important; } }

Firefox's interface changes over time. That is one of the reasons that userChrome.css files are not officially supported.

Whose files are you using to color the folders? The ones from the Classic repository might be updated by now. There is an active thread here with user workarounds:

If you are using a file or copy/pasted code from my site, I updated it Saturday:

Hi

Thanks for the quick reply and detailed help, I managed to get the yellow folders back (the older style solid yellow ones), using the links you provided.

Hopefully it's a while before another update removes them again!!

thanks again Neil
